Thanks for all the advice. We'd just be running it on single buffers so I agree it makes more sense to start from the rust regex library than ripgrep. We do however need to continue supporting backrefs and lookaround, so we'll need to add `--auto-hybrid-regex` functionality to fall back to either Node's engine or a webassembly PCRE2. As for wasm vs FFI, it would ideally work in browser (Monaco), which makes wasm the best bet I believe.

Ah yeah, for backrefs you'll need to find a way to use PCRE2. Not sure what the WASM story is there. But at that point, if your only problem with Node regexes is catastrophic backtracking, then you might as well just stick with Node. PCRE2 will have the same problem.
